Jet 321970 Engine Lathe 18 in Swing 80 in Centers 7.5HP

Product Description

The JET 321970 is a heavy-duty gap bed engine lathe built for professional machine shops and industrial environments. It delivers 18 inches of swing over the bed and 80 inches between centers, making it capable of turning large-diameter and long-length workpieces. The D1-8 Camlock spindle mount provides fast, repeatable tooling changes without compromising rigidity. Power comes from a 7.5 HP motor running on 3-phase current at 230 or 460 volts. At 6,790 pounds, this is a full-size production lathe intended for licensed machinists and industrial maintenance professionals performing precision turning, threading, boring, and facing operations.

This lathe is suited for heavy industrial and commercial machine shop use where large-swing capacity and long-bed center distance are required. Typical applications include shaft work, tooling fabrication, and custom part production across metalworking trades. The 230/460V dual-voltage configuration gives flexibility for shops running either standard industrial service voltage, and the 3-phase requirement makes it appropriate for dedicated production floor installations rather than light-duty or single-phase shop setups.

Key Features

• 18-inch swing over bed accommodates large-diameter workpieces
• 80-inch center-to-center distance supports long shaft and bar stock
• D1-8 Camlock spindle nose for fast, secure chuck and fixture changes
• 7.5 HP motor for high-torque cutting across a wide range of materials
• 3-phase, 230/460V dual-voltage motor for flexible industrial power hookup
• Substantial 6,790-pound machine mass for vibration damping and rigidity

Compatibility

Designed as an OEM-matched replacement and production machine within the JET GH-1880ZX lathe platform. Specific chuck, faceplate, and tooling compatibility is limited to D1-8 Camlock-standard accessories.

Installation Notes

Installation requires a licensed electrician for 3-phase 230/460V service connection in accordance with NEC requirements. The machine must be set on a level, reinforced concrete floor rated for the 6,790-pound static load, and anchor bolt placement should follow the manufacturer leveling and anchoring procedure. Disconnect and lock out all power before performing any spindle, chuck, or electrical service work. Commissioning should be completed by a qualified machinist or millwright familiar with engine lathe alignment and test cuts.
